This section explains how to share data between Universal Windows Platform (UWP) apps, including how to use the Share contract, copy and paste, drag and drop, and app services.
The Share contract is one way users can quickly exchange data between apps. For example, a user might want to share a webpage with their friends using a social networking app, or save a link in a notes app to refer to later. Consider using a Share contract if your app receives content in scenarios that a user can quickly complete while in the context of another app.
An app can support the Share feature in two ways. First, it can be a source app that provides content that the user wants to share. Second, the app can be a target app that the user selects as the destination for shared content. An app can also be both a source app and a target app. If you want your app to share content as a source app, you need to decide what data formats your app can provide.
In addition to the Share contract, apps can also integrate classic techniques for transferring data, such as dragging and dropping or copy and pasting. In addition to communication between UWP apps, these methods also support sharing to and from desktop applications.
UWP apps can also create app services that provide functionality to other UWP apps. An app service runs as a background task in the host app and can provide its service to other apps. For example, an app service might provide a bar code scanner service that other apps could use.
